Where was Miss Shirley while I was at the museum, you ask?
Miss Shirley knows how to do vacation. No getting up at the crack of 9 a.m. to eat breakfast and race off to a museum. Nuh-uh. Instead, send your friend to the museum while you sleep until 1:00, then get the friend to tell you about the exciting parts over lunch.
She was coming down with a cold, so spending 18-20 of every 24 hours in bed was not a bad idea at all, but this was her plan even pre-illness. It's vacation genius.
